IBM T42 gives Fan Error message and stops

My IBM notebook T42 gives FAN ERROR message and switches off. It is an intermittent problem and many times I am unable to get it started. Once I was able to get it working, since then I have not switched it off. I just close the LCD panel and put it in hibernation mode. I can also reboot in this mode during automatic updates. This seems to be BIOS problem connected with some hardware. The Lenovo service center failed to identify the problem. Are the schematic circuit diagrams available to trace this problem? I also want to know if I can use larger hard disk than 80 GB that came with the machine. If so what is the maximum limit. Is BIOS upgradation needed for this and how do I do it.

The fan may be faulty or clogged with dust.
Check the fan to see f it spins freely and remove dust from the heatsink fins and fan assembly.

The specification in the manual for the T40 series shows the largest hard drive is 80 Gb.
It may be possible to install a larger hard drive, but check with Lenevo first.

Fan error displace on my t42 ibm.I noticed the fan is working but the error do come once in a while thereby prevent the pc from working


If the fan is running but your notebook still overheats, your computer will turn itself off, and you need to wait until it cools down

The question is, why is it overheating? Try using a vacuum cleaner close to the ventilation slots to suck out any dust.

If this does not solve the problem, please get back to me

My ThinkPad T42 cooling fan works slow... i feel like air flow is very slow when i touch the vents... i opened the laptop and checked the fan and it was really slow.. what should i do now please help......


You should replace the fan if it is defective.

You can check inside your Bios or System Setup to see if there are any options on controlling the fan. If the laptop is not giving you any error messages or overheating the fan might be ok.

Cleaning the fan may help. I use a vacuum cleaner and hold the pipe against the air inlet of the computer and then against the exhaust outlet. That clears the fluff quite easily.
Hope this helps.

Fan Error message but the fan's working on another machine


One option would be to replace the motherboard. You can use one from T40 -T43 with your monitor. I bought one on Ebay for $90 which came with the board installed to the bottom plastic tray. I only had to install my monitor, memory, keyboard, hard drive, & plastic bezel and I had a good working unit for $90.

IBM t42 comes on, beeps twice and goes off, connected and battery


Yes it is the fan, get a can of compressed air and clean the air vents and the CPU fan with that, also i would check into the CMOS battery as it could be dead and needs replacing.
As the laptop starts up hit F1 when you see the IBM logo and check the date and time, that will be a clear indicator IF the CMOS battery is dead because it will not be the right date and time, it should however let you into windows if you put the date and time right (it may take a couple of attempts)


Good luck

IBM T42 gave fan error, replaced and can not get it to reboot


make sure the fan is pluged in correctly and you didnt unplug anything else such as memory or etc or bump the cpu... did you put any thermal paste on the cpu when you put the fan on it? its needed to bond the too together to make a better cooling system there maybe a setting in your bios to disable fan monitoring or cpu temp etc have to look at your bios to see

IBM T42 laptop...NO Video, laptop powers up however fan spins however...ideas???


Connect the laptop to an external monitor, you may have to hold down the Function key and press the F8 or F7 CRT/LCD key to switch between monitor and display, to see if the video card is defective.
I hope this helps solve your problem.
Good Luck.

IBM Lapyop T42-message"Fan errors" does not turn on


your cooling fan is reporting as damaged you need to replace the fan unit (cooling pad as well) likely service is required and unless you want to disassemble your laptop a service center would be better suited for this job.
